25、deration of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that com
26、mittee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the
27、technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. International Standard ISO 140-6 was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 2, Building
28、 acoustics. This second edition cancels and replaces the first edition (ISO 140-6:1978), which has been technically revised. ISO 140 consists of the following parts, under the general title Acoustics Measurement of sound insulation in buildings and of building elements: Part 1: Requirements of labor
29、atory test facilities with suppressed flanking transmission; Part 2: Determination, verification and application of precision data; Part 3: Laboratory measurement of airborne sound insulation of building elements; Part 4: Field measurements of airborne sound insulation between rooms; Part 5: Field m

33、 140-6:1998 BSI 05-19991 1 Scope This part of ISO 140 specifies a laboratory method for measuring impact noise transmission through floors by using a standard tapping machine. The method is applicable to bare floors and also to floors with coverings. The results obtained can be used to compare the i
34、mpact sound insulation properties of floors and to classify floors according to their sound insulation capabilities. NOTE 1Field measurements of impact sound insulation of floors are dealt with in ISO 140-7. NOTE 2Laboratory measurements of the reduction of transmitted impact noise by floor covering
35、s on a heavyweight standard floor are dealt with in ISO 140-8. 2 Normative references The following standards contain provisions which, through reference in this text, constitute provisions of this part of ISO 140. At the time of publication, the editions indicated were valid. All standards are subj
36、ect to revision, and parties to agreements based on this part of ISO 140 are encouraged to investigate the possibility of applying the most recent editions of the standards indicated below.

40、 logarithm to the base 10 of the ratio of the space and time average of the sound pressure squared to the square of the reference sound pressure, the space average being taken over the entire room with the exception of those parts where the direct radiation of a sound source or the near field of the
41、 boundaries (wall, etc.) is of significant influence; it is expressed in decibels if a continuously moving microphone is used, L is determined by where if fixed microphone positions are used, L is determined by where p1, p2 ., pn are r.m.s. sound pressures at n different positions in the room. In pr
42、actice, usually the sound pressure levels Lj are measured. In this case L is determined by where Lj are the sound pressure levels L1 to Ln at n different positions in the room 3.2 impact sound pressure level, Li average sound pressure level in a one-third-octave band in the receiving room when the f
43、loor under test is excited by the standardized impact sound source; it is expressed in decibels .(1) pis the sound pressure, in pascals; p0is the reference sound pressure and is equal to 20 4Pa; Tmis the integration time, in seconds. .(2) .(3) Licensed Copy: sheffieldun sheffieldun, na, Mon Nov 20 0

47、erwise stated by the equipment manufacturer, a sound calibrator which complies with the requirements of accuracy class 1 defined in IEC 60942 shall be used. For sound level meters calibrated for measurements in sound fields of progressive plane waves, corrections for the diffuse sound field shall be
